SEATEL 120hdtv

From what little info I can find on that dish is it only has 1 "F" type connector so it can't work with a SWM8 module.  I don't know if that F connector is SWM or not.

3.4. NO Shipping Restraints
There are NO shipping restraints to remove from this antenna.
NOTE: The motors on this antenna have brakes, which automatically engage
when power is turned OFF, or is lost. Shipping restraints are not required on
this equipment.
After installation, when Power is turned ON, the brakes on the motors will release and allow the antenna to be
driven.
3.5. Installing the Below Decks Equipment.
3.5.1. General Cautions & Warnings
CAUTION - Allow only an authorized dealer to install or service the Sea Tel
System components. Unauthorized installation or service can be dangerous and may
invalidate the warranty.
3.6. IF Coax Cable Connections
Refer to the System Block Diagram. Connections are described using the color designation as show on the System
Block Diagram.
3.6.1. Red Coax
This coax provides +24 VDC power to the antenna and it also carries the Ethernet Over Coax (EOC)
antenna control signals between the antenna and the LMXP. Connect this coax to J2 Antenna
connection on the rear panel of the LMXP (this step is duplicated below).
3.6.2. Blue Coax
This coax carries the Low Band Vertical/RHCP signals from the antenna to a splitter.
One output of the splitter goes to the below decks Multiswitch, or other distribution equipment that is
feeding the Ku-Band satellite receivers. Connect this output to the Low Band Vertical, or RHCP port, on
your Multiswitch, or other distribution equipment.
Connect the other output from the splitter to the Low Band RHCP (13V) port, on your 8 CH SWM which
feeds your DirecTV HD receivers.
3.6.3. White Coax
This coax carries the Low Band Horizontal/LHCP signals from the antenna to a splitter.
One output of the splitter goes to the below decks Multiswitch, or other distribution equipment that is
feeding the Ku-Band satellite receivers. Connect this output to the Low Band Horizontal, or LHCP port, on
your Multiswitch, or other distribution equipment.
Connect the other output from the splitter to the Low Band RHCP (18V) port, on your 8 CH SWM which
feeds your DirecTV HD receivers.
3.6.4. Green Coax
This coax carries the High Band Vertical/RHCP signals from the antenna to a splitter.
One output of the splitter goes to the below decks Multiswitch, or other distribution equipment that is
feeding the Ku-Band satellite receivers. Connect this output to the High Band Vertical, or RHCP port, on
your Multiswitch, or other distribution equipment.
Connect the other output from the splitter to the High Band RHCP (13V+22KHz) port, on your 8 CH SWM
which feeds your DirecTV HD receivers.
3.6.5. Black Coax
This coax carries the High Band Horizontal/LHCP signals from the antenna to a splitter.
One output of the splitter goes to the below decks Multiswitch, or other distribution equipment that is
feeding the Ku-Band satellite receivers. Connect this output to the High Band Horizontal, or LHCP port,
on your Multiswitch, or other distribution equipment.
Connect the other output from the splitter to the High Band LHCP (18V+22KHz) port, on your 8 CH SWM

You need a grey 29v power inserter for the SWM8.
